A caisson permit has been issued for a mixed-use development at 4006 N. Sheridan in Chicago's Uptown neighborhood. Planned by Catapult Real Estate Solutions, the 7-story building will replace the existing apartments and storefronts with 91 residential units and 2,050 square feet of retail space.

Why it matters

This development is part of the ongoing transformation of the Uptown neighborhood, which has seen a mix of new residential and commercial projects in recent years. The reduction in required parking spaces and elimination of a loading berth also reflect the city's efforts to encourage more transit-oriented, pedestrian-friendly development.

The details

The development, designed by Built Form LLC, will include 11 studio units, 46 one-bedroom units, and 34 two-bedroom units. Rents are expected to range from $1,700 for studios to $2,500 for two-bedrooms. The ground floor will feature the residential lobby, a bike room, and 2,050 square feet of retail space. Upper floors will have a shared workspace, fitness center, and a community amenity space on the seventh floor.

  • The Zoning Board of Appeals approved variations for the project in 2025.
  • The caisson permit was issued in April 2026, allowing construction to begin.
